Say oxygen in the Earth's crust but I believe i's different in the mantle, nitrogen in the local atmosphere

It's oxygen (air, water and the 16 km broad earth's crust)
The weight component in earth's crust is projected at 49.5 %.
e.g. sand is silicium dioxide ...
air alone is mostly composed of nitrogene
